You sit at your desk and place your hands on the computer keyboard to start typing an email or message. Your fingers instinctively rest on the middle row of keys, ready to move.
Look more closely at the F key on the left and the J key on the right. These keys stand out because of the small raised bumps on their surfaces, a detail that blends into the routine of typing.
These bumps are positioned exactly where the index fingers naturally settle during typing. When felt by touch, they confirm that the hands are aligned on the home row: the left index on F, aligning A, S, D beneath the other fingers; the right index on J, aligning K, L, and semicolon similarly.
This design choice enables a repeatable hand position. It guides the fingers back to the starting layout after pauses or shifts, supporting a smooth progression through sequences of keystrokes.
The bumps constrain placement to these specific spots, optimizing the keyboard for ordered, efficient entry of text across long sessions. They direct the physical flow of interaction from rest to active input.
The keyboard's surface is not a uniform plane. These tactile markers reveal intentional shaping of how hands engage with it, moment by moment.
